What is the proper method for completing Lewis Dot
Structures?
Template byBill Arcuri, WCSD
1. Sum of valence electrons.2. Write symbols for atoms.
3. Connect with single bonds.4. Complete the octets of atoms
bonded to the central atom.5. Place leftover electrons on
the central atom.6. If there are not enough form
a double bond.
